Problems solved by technology

[0004] However, during the first water conditioning process of wheat, it is easy to breed a large number of Bacteria, the water used for conditioning is ordinary water, which does not have the ability to sterilize bacteria, so the bacterial content of the wheat flour obtained after post-processing increases, the storage period of the flour is short, and it is prone to mildew

Embodiment 1

[0016] A wheat conditioning and sterilization method, adding 4% water (the water content of the original wheat is 12%) to the raw wheat after impurity removal, so that the water content in the wheat is kept at 16%, and then sent to the wheat moistening warehouse for 28 hours to moisten Wheat is then sent to the secondary conditioning bin, where 0.5% of the wheat’s weight of ozone-saturated water is added by spraying water, and then placed for 1 hour and sent to the subsequent grinding and milling system (including five skin mills, two slag mills, seven Heart milling, two-stage tail milling, ten-stage flour clearing, impact-assisted flour extraction, and back-stage bran beating; this process flow is a conventional technology in the field, so it will not be described in detail) to obtain flour.

Embodiment 2

[0018] A wheat conditioning and sterilization method, adding 5% water to the raw wheat after impurity removal (the water content of the original wheat is 10%) to keep the water content in the wheat at 15%, and then sending it to the wheat moistening warehouse for 36 hours to moisten Wheat, then sent to the secondary tempering bin, adding ozone-saturated water accounting for 1.0% of the wheat weight by spraying water, and then placed for 1.5h and sent to the subsequent grinding and milling system (including five skin mills, two slag mills, Seven-way heart mill, two-way tail mill, ten-way powder clearing, impact-assisted flour extraction, and back-road bran beating; this process flow is a conventional technology in this field, so it will not be described in detail) to obtain flour.

Abstract

The invention relates to a wheat conditioning and sterilizing method. Water is added in wheat without impurities, the content of water in the wheat is remained between 15% and 16%, the wheat is then conveyed to a wheat wetting bin to be wetted in a standing manner, ozone saturated water is added in the wheat after the wheat is wetted by a spraying watering method, wherein the weight of the ozone saturated water is 0.5% to 1.0% of that of the wheat after the wheat is wetted, and then the wheat is conveyed to a follow-up grinding and milling system after standing for 1 to 1.5 hours. In the process, the ozone saturated water is used for secondarily conditioning the wheat, various bacteria bred in the wet wheat after primary conditioning can be effectively killed, the content of the bacteria in flour obtained after later-stage processing is low, quality guarantee period of the flour is long, and the floor is white and does not have toxic and side effects to human bodies.

Description

technical field [0001] The invention belongs to the technical field of wheat flour milling technology, and in particular relates to a conditioning and sterilization method in the wheat flour milling technique. Background technique [0002] The existing traditional wheat flour milling process generally includes impurity removal→conditioning→grinding milling. At present, the commonly used milling systems in China include skin milling system, slag milling system, powder cleaning system, core milling system and tail milling system. The leather milling system is the first few grinding systems in the milling process. Its function is to peel off the wheat grains, separate the wheat dregs, wheat heart and coarse flour, and keep the bran flakes from being too broken, so that the endosperm and wheat bran Separate for maximum and raise a small amount of wheat flour. The slag mill system is used to process the endosperm particles with wheat husks separated from the husk mill and othe...
